HEATER.

Application filed June 10, 1926. Serial No. 115,084.

My invention relates to a heater and it is an object thereof to provide a. simple and inexpensive device of this character which shall be adapted to cooperate with a gas burner such as the Bunsen burner in such a manner as to protect the flame from draughts, prevent any danger of fire. and provide for uniform and even distribution to the heat of the flame in such a manner as to give a highly improved heating effect, thereby increasing the heating action of the burner and prolonging the heating effect.

Referring to the drawings, which are made a part hereof, and in which similar reference characters indicate similar parts:

Figure 1 is an elevation of my improved device with parts broken away, Figure 2, a transverse section, and Figure 3, a partial longitudinal section. i

In the drawings reference character 10 indicates supporting means for spacing the body of the device from the floor. As will be understood such supporting means may take any desirable or conventional form, these parts as well as the remainder of the device being conveniently I constructed of sheet metal. A body 11 is supported by the parts 10, said body being shown as hollow to provide an air chamber of considerable extent into which the air enters at 12 through an opening surrounding the lower part of the burner 13 to which gas is conveyed by a pipe 14. in ordinary manner. It will be understood that other types of burners may be used and other fuel than gas may be utilized as desired.

Above the body 11 and con'nnunicating directly with the air chamber therein I have provided a series of extensions 15. These extensions in the form here shown are rectangular in cross section and may extend from side to side of the body 11. The extensions are each similar to the others and are arranged in parallelism, the arrangement and size of these parts being such as to afford a free circulation of air between and aboutthem. As will be seen they are of considerable height as compared with their width and thickness.

At the upper end of each extension 15 there is provided a door 16 hinged at 17, the arrangement being such that the door can readily be lifted to afford access to the interior of the extension and to some extent, to afford access tothe interior of the body 11. The arrangement of doors is such that in the case of sudden expansion inside the heater. as when gas is lighted after starting, the doors can open to permit the gases to escape Without damaging the remainder-of the device.

For heating rooms of dwellings, stores and the like it is found that my arrangement gives a better heat distribution and apparently a greater heating effect than the open burner, such effect being also more lasting by reason of the hot air confined in the heater. In addition to this the flame is steady and is prevented from burning objects approaching 1b.

Having fully described my said invention what I claim as new and desire to secure by Letters Patent is 1. A heater of sheet-metal comprising an elongated hollow body of rectangular section merging into integral supports of similar shape, said body and supports having a flat top lying in a common plane and having an aperture midway of the under side of the body to receive a burner, said body also having a plurality of rectangular openings in its flat top extending approximately from one side of the top to the other, a set of parallel rectangular upright extensions correspond mg to said openings and permanently fixed to the body, and sheet-metal closures for the upper ends of said extensions covering the same and hinged along one edge thereof.

2. A heater comprising an elongated chamber forming a base provided with means for admitting air, and a plurality of independent parallel tubular members spaced from each other mounted on and communicating with said base, the upper ends of said tubular members being provided with closures adapted to be automatically lifted to provide for excessive pressure of the gases in said members.

In testimony whereof I affix my signature.
